We recently toured the Greenhouses with Boyce Tankersley, director of living plant documentation, to see what’s in bloom and take in the different climates visitors can enjoy.

In the Arid Greenhouse, we saw a number of species of aloe from South Africa just coming into bloom as well as cacti and succulents.

In the Tropical Greenhouse, we were surrounded by palms and cycads while we admired the many orchids in bloom. Tankersley pointed out the acanthus cultivar (Aphelandra sinclairiana ‘Panama Queen’) native to Panama and Costa Rica, as one of his favorites.

The Semitropical Greenhouse was filled with blooms like pinkball dombeya (Dombeya wallichii). Native to East Africa and Madagascar, the genus is a highly sought-after ornamental in USDA Zones 9 and warmer.

One of the rarest plants in our collections is Deppea splendens. Native to the mountains of western Mexico, this plant is extinct in the wild.

Visit our What’s in Bloom highlight page each week — twice a week during the summer bloom season — to learn more about the different plants in bloom. Then, come out to see them in person for their fragrance and the humidity of the warmer greenhouse climates.
